Of course, their ideology has little to do with an actual concern for the Earth and mankind's future on it. They are driven by a desire to clamp down and control the human population, and socially engineer it to weed out the undesired and unneeded. In order to save the planet, "human populations must be greatly diminished, and as quickly as possible."
Desperate in the face of growing skepticism, driven largely by their relentless and obviously fallacious fear mongering, the so-called scientific community just compounds the ludicrous. We now have "just four months. Four months to secure the future of the planet."
- If we fail to act, climate change will intensify droughts, floods and other natural disasters.
Water shortages will affect hundreds of millions of people. Malnutrition will engulf large parts of the developing world. Tensions will worsen. Social unrest – even violence – could follow.
The damage to national economies will be enormous. The human suffering will be incalculable.
It's pretty much moot to point out the absurdities of these claims, because nobody takes them seriously anyway, but suffice it to say that the Earth stopped warming circa 1998, and that we know of a period in the Earth's history - the Medieval Warming Period - in which temperatures were comparable to today's temperatures, but over a much more sustained period - approximately 400 - 500 years. According to the Oxford Companion to the Earth,
- The Norse colonization of Greenland and Iceland—itself probably made possible only by the moderation in climate—provided a legacy of records in a climatically sensitive zone. Indeed, high latitudes provide the most emphatic evidence for increasing temperature. This is usually attributable to variations of sea ice; for most of the eleventh and twelfth centuries the waters around Iceland and southern Greenland were largely clear of ice.
The discovery early in the twentieth century of plant roots and Norse burial grounds in subsequently frozen soil suggests that temperatures were 2–4 °C higher than in the twentieth century. A chronology of annual temperature for Iceland, derived from sea-ice records, indicates a peak of warmth around 1100 ad, a finding confirmed by evidence of agricultural prosperity: the largest surviving foundations of farmhouses are of Norse origin.
Central European vineyards have been found at elevations more than 200 m higher than today, indicating that summers were up to 1.5 °C warmer. Vineyards spread northwards as well as upwards; they were quite widely distributed over southern England. This implies a freedom from late spring frosts, and summers that were relatively dry and sunny.
Somehow, the Earth didn't wither and die. The polar bears didn't die off. Rather than "incalculable suffering", human civilization thrived. Surely there were droughts, and floods, and other natural disasters, but if you're even a novice student of geographical history, Earth has experienced far worse natural disasters, long before the emergence of humanity, much less the emergence of the SUV.
But the alarmists would like you to believe you're not smart enough, you lack the expertise to draw rational conclusions, or interpret empirical evidence, despite the fact that tens of thousands of scientists now openly dispute that global warming is caused by man. Just pay your carbon taxes and leave it to them, they'll do the thinking for you. And if you happened to notice summer is mysteriously missing this year, pay it no mind. It's not global warming anymore, anyway. It's climate change. No matter what the Earth does, it's your fault.
